Its 1.24 V internal reference lets it regulate down where a TL431 bottoms out, making it the natural fit for 1.8 V and 3.3 V supply supervision, low-voltage bias generation, and feedback loops in modern POL converters. ## 80 µA cathode current — why it matters for battery bias Minimum cathode current is 80 µA, an order of magnitude lower than the TL431's 1 mA typical. In a battery-powered feedback divider or a micropower reference, that difference saves 0.9 mA of standing current — enough to extend shelf life in a coin-cell application or keep a sleep-mode supply within budget. ## SOT-23-5: the fifth pin is a Kelvin sense The TLV431CDBVR comes in a 5-pin SOT-23-5 (SC-74A) package. For a precision shunt with ±1.5% initial tolerance, that Kelvin connection recovers about half the tolerance budget that a standard three-pin shunt would lose to trace resistance.
